摘要:
There is provided a liquid crystal display control device which can display pictures in a magnification mode by using only a memory having low-speed access and a low storage capacity. When a video signal has intermediate resolution or less, the enlargement processing is performed by a frame memory, a line memory and an enlargement processing control circuit. If the input operation and the output operation to and from the frame memory are synchronized with each other, it is sufficient for the frame memory to have a storage capacity of two lines. When the video signal has the same high resolution as a liquid crystal display panel, the video signal is output through a gate circuit to a display timing generating circuit, and it is displayed in a through mode. In this case, no processing is performed by the frame memory or the like.

An information recording method using an optical recording medium includes the steps of forming a plurality of recording pulses to irradiate the optical recording medium and recording information to the optical recording medium by irradiating the recording pulses on the optical recording medium. At least a leading edge of a first recording pulse and a trailing edge of a last recording pulse of the recording pulses shift at a shifting value, wherein the shifting value is determined by combinations of a length of M(n) of a mark being currently written and at least one of a length s(n−1) of a space precedent to the mark and a length s(n+1) of a space subsequent to the mark.

A liquid crystal display device for displaying video data having a detection circuit for detecting a luminance distribution based on video data which is inputted, the luminance distribution being indicative of generation frequency of gradations in each of divided region which includes a plurality of gradations. The display device includes a determination circuit for determining at least one of a plurality of divided regions of higher generation frequency of gradation than that of other divided regions based on the luminance distribution, a correction circuit for correcting the video data so as to make a luminance characteristic of the at least one of the plurality of divided regions of higher generation frequency of gradation more abrupt than a luminance characteristic of the other divided regions, and a liquid crystal display panel for displaying the corrected video data. A width of the divided region is changeable.
摘要:
An information recording medium comprising a plurality of layers for recording or reproduction of information by optical irradiation. Each of the layers of the recording medium includes asperities made up of a groove, wherein the groove in each of the layers has wobbles of a first frequency and wobbles of a second frequency that is different from the first frequency within a single track. The first frequency is constant in each of the layers, and a different signal is obtained from the wobbles of the first and second frequencies in each of the plurality of layers.

An information reproducing apparatus includes a rotating portion to rotate an information recording medium on which information has been recorded by wobbling borders on both sides of a track with different phases; a beam irradiating portion for irradiating a beam spot on the track of the information recording medium; a photodetector for receiving a reflected beam of the beam spot from the information recording medium; a detector for detecting a composite waveform including waveforms on the borders on both sides from the received beam intensity of the photodetector; a phase change detector for detecting changes in the phase of wobbling waveforms on the borders on both sides from the composite waveform; and an information reproducer for reproducing information corresponding to detection result of the phase change detector by using a predetermined relation between phase changes and information.
摘要:
An optical information reproducing method for reproducing information recorded at at least one mark on an optical information medium. The method includes irradiating a laser to the optical information medium, detecting a reflected beam reflected from the optical information medium, and reproducing information recorded on the optical information medium from an output signal of a detector which detects the reflected beam. The step of reproducing information is changed in dependence upon a length of the mark of the optical information medium.

In the electric power system protective control system, a plurality of protective control apparatuses each having a protective control function to an electric power system are distributed and connected through a communication network to each other so that data communication is permitted among the respective protective control apparatuses. Each of the protective control apparatuses is carried out a process of executing a control operation related to the protective control function of the own apparatus according to a program module. The program module migrates through the communication network to the own apparatus along a predetermined route of migration. Each of the protective control apparatuses executes a process of migrating the program module from the own apparatus to another protective control apparatus. The another protective control apparatus is determined to a next destination of migration according to the route of migration. In a case where the program module is not migrated by the migration process to the next destination protective control apparatus, each of the protective control apparatuses executes a process of changing a next destination of migration of the program module to a predetermined protective control apparatus except for the next destination protective control apparatus, making it possible to prevent the program module from stopping.

In a valve-operating mechanism in a 4-cycle engine, a timing transmitting device is disposed on one side of an engine body. A cam device includes a cam coupled to a driven pulley of the timing transmitting device on one side of a cylinder head, intake and exhaust rocker shafts rotatably carried in the cylinder head, intake and exhaust cam followers secured to one ends of the rocker shafts with their tip ends in sliding contact with the cam, and intake and exhaust rocker arms secured to the other ends of the intake and exhaust rocker shafts with their tip ends abutting against the intake and exhaust valves. Thus, the cam of the cam device can be disposed on one side of the cylinder head to effectively reduce the entire height of the engine.

A lithium secondary battery according to the present invention comprises: a positive electrode having a positive electrode active material composed of a reversible lithium intercalation material; a negative electrode having a negative electrode active material composed of a reversible lithium intercalation material; and a separator interposed between said positive electrode and said negative electrode, and in the positive electrode active material, at least one material which shows a positive sign of a total sum of entropy heat from a discharged state to a charged state is mixed with at least one material which shows a negative sign of a total sum of an entropy heat from a discharged state to a charged state. In a battery having such a construction, the amount of entropy heat during charge is reduced compared with a battery employing only a material which shows a positive sign of the total sum of entropy heat. As a result of this, a battery produced in accordance with the present invention achieves an improved cycle characteristic, and thereby is capable of preventing a large deterioration of a battery performance.
